I’ve been reloading for better than 50 years. I almost always stick with U.S. manufactured commercial brass from Winchester, Remington and Federal. I avoid PMC and Hornady brass due to problems I’ve experienced with this stuff being too darn hard to do anything with. Yesterday I was re-sizing some once fired 270 Winchester brass and decided to go with the last of some Federal (FC) brass I had on hand. I’ve used Federal for years and had no problems. Anyway, I resize, trim and clean 100 rounds of brass (50 Federal and 50 Remington). Every bit of the Federal brass had primer pockets that were too large. The primers (Winchester Large Rifle) would seat but there was almost no resistance felt when seating the primers and I could take a small punch, run it down inside the case and push the primers out with no more than light finger pressure. Sure, every once in a while you’ll run across a case with an over-size primer pocket. Who doesn’t...but 50 straight??? Anybody ever run into this before on this scale?
